Coins with unknown stamps on them [solved]

I am trying to figure out what the stamps are on these coins. I am fairly certain the identification is accurate.

The 20 Para has one stamp that looks like “PM”

The 40 Para has 2 stamps, one on each side. One has characters I can't identify,  possibly a “K”. The other side is also unidentifiable, one is an “X”?

40 Para N#10137

20 Para N#20387

Any information is appreciated.
